CONTRACTION JOINT FOR INTELLIGENT COMPLETION AND DOWNHOLE COMPLETION SYSTEM
A contraction joint includes a mandrel at least partially disposed within an upper tubular member, the upper tubular member being capable of moving uphole and downhole to change a length of the contraction joint. The contraction joint also includes a nipple housing connected to the upper tubular member, a piston housing connected to the nipple housing, a support piston disposed in the piston housing, the support piston being affixed to an upper mandrel sub of the mandrel via at least one piston retaining device, a lock housing disposed between the upper tubular member and the upper mandrel sub, and a stroke locking mechanism disposed within the lock housing, the stroke locking mechanism including a profile that engages the nipple housing.
The present application claims priority benefit of U.S. Provisional Application No. 63/170,090, filed Apr. 2, 2021, the entirety of which is incorporated by reference herein and should be considered part of this specification.
BACKGROUNDIn many well related operations, contraction joints are used with well completions, such as between two or more completion assemblies, to compensate for contraction and expansion of the completion string. Wellbore completions typically utilize one or more control lines to carry signals between components within the wellbore and/or the surface. It can be difficult to control or maintain the integrity of those control lines at a contraction joint because axial movement of the contraction joint can cause the lines to knot or tangle as the contraction joint expands or contracts. Moreover, it may be difficult to control the functionality of the contraction joint until the contraction joint reaches a desired depth downhole and to accommodate production operations at depth through the contraction joint. There is a need, therefore, for a contraction joint that can accommodate control lines, and that remains locked until a desired depth downhole is reached to facilitate production operations.
SUMMARYAccording to one or more embodiments of the present disclosure, a contraction joint includes an upper tubular member having a bore therethrough; a mandrel including: an upper mandrel sub including a port; a lower mandrel; and a mandrel crossover connecting the upper mandrel sub to the lower mandrel, wherein the mandrel is at least partially disposed within the upper tubular member, wherein the upper tubular member is capable of moving uphole and downhole to change a length of the contraction joint; a nipple housing connected to the upper tubular member; a piston housing connected to the nipple housing and the lower mandrel; a support piston disposed in the piston housing, the support piston being affixed to the upper mandrel sub of the mandrel via at least one piston retaining device, a lock housing disposed between the upper tubular member and the upper mandrel sub of the mandrel; and a stroke locking mechanism disposed within the lock housing, the stroke locking mechanism including a profile that engages the nipple housing, wherein, in a locked position, the stroke locking mechanism is supported by the support piston, and the profile of the stroke locking mechanism prevents the nipple housing from moving.
However, many modifications are possible without materially departing from the teachings of this disclosure. Accordingly, such modifications are intended to be included within the scope of this disclosure as defined in the claims.
Certain embodiments of the disclosure will hereafter be described with reference to the accompanying drawings, wherein like reference numerals denote like elements. It should be understood, however, that the accompanying figures illustrate the various implementations described herein and are not meant to limit the scope of various technologies described herein, and:
In the following description, numerous details are set forth to provide an understanding of some embodiments of the present disclosure. However, it will be understood by those of ordinary skill in the art that the system and/or methodology may be practiced without these details and that numerous variations or modifications from the described embodiments may be possible.
In the specification and appended claims, the terms “connect,” “connection,” “connected,” “in connection with,” and “connecting,” are used to mean “in direct connection with,” in connection with via one or more elements.” The terms “couple,” “coupled,” “coupled with,” “coupled together,” and “coupling” are used to mean “directly coupled together,” or “coupled together via one or more elements.” The term “set” is used to mean setting “one element” or “more than one element.” As used herein, the terms “up” and “down,” “upper” and “lower,” “upwardly” and “downwardly,” “upstream” and “downstream,” “uphole” and “downhole,” “above” and “below,” “top” and “bottom,” and other like terms indicating relative positions above or below a given point or element are used in this description to more clearly describe some embodiments of the disclosure. Commonly, these terms relate to a reference point at the surface from which drilling operations are initiated as being the top point and the total depth being the lowest point, wherein the well (e.g., wellbore, borehole) is vertical, horizontal, or slanted relative to the surface.
The present disclosure generally relates to a system and methodology that facilitates the use of a contraction joint in a well completion application. Specifically, the present disclosure relates to a contraction joint that includes a stroke locking mechanism that allows the contraction joint to remain locked when running in hole, and allows the contraction joint to achieve contraction functionality at depth downhole. Advantageously, the contraction joint according to one or more embodiments of the present disclosure accommodates one or more control lines and facilitates production operations at depth when in the unlocked position.
